Question

Find the area and perimeter of the given figure ​

Answer 1

Answer:

Perimeter of rectangle =70m

Step-by-step explanation:

Perimeter of rectangle - 2( length+breadth)

Length - 20

Breadth - 15

= 2( 20 + 15)

2×35

=70m

Perimeter of rectangle =70m

I hope it is helpful for you.

Answer 2

Question:

Find the area and perimeter of the given figure.

____________________________________________________________________

Solution:

We Can See that the fig is int the shape of Rectangle. Firstly We Can Find the Perimeter Of This Fig.

____________________________________________________________________

$perimeter \: of \: this \: fig.\longrightarrow 2(l + b) \\ \longrightarrow 2(20 + 15) \\ \longrightarrow 2 \times 35 \\ \longrightarrow 70cm$

So, The Perimeter Of This Fig. Is 70cm.

____________________________________________________________________

Now,

According To My Fig.

length of shaded portion is 15m

$bredth = 20 -( 5 + 5) \\ = 10m$

____________________________________________________________________

$area \: of shaded \: portion ( according \: to \: my \: fig.) \\ \longrightarrow l \times b \\ \longrightarrow 15m \times 10m \\ \longrightarrow {150m}^{2}$

____________________________________________________________________

We can clearly see that.. in this Fig. there is 4 square with equal Side.

side of square is 5m

so,

____________________________________________________________________

$area \: of \:1 \: square\longrightarrow {(a)}^{2} \\ \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \longrightarrow {(5)}^{2} \ \\ \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \longrightarrow {25m}^{2}$

____________________________________________________________________

Now, For the 4 Square

$area \: of \: 4 \: square\longrightarrow 4 \times area \: of \: 1 \: square \\ \longrightarrow 4 \times {25m}^{2} \\\longrightarrow {100m}^{2}$

____________________________________________________________________

Now, We Can See that There is Small Rectangle Also

So,

The Length Of that Rectangle is 10m

Breadth is 5m.

$the \: area \: of \: that \: rectangle\longrightarrow l \times b \\ \longrightarrow 10 \times 5 \\ \longrightarrow {50m}^{2}$

____________________________________________________________________

Now,

____________________________________________________________________

$area \: of \: the \: given \: fig \longrightarrow area \: of \: shaded \: portion + area \: of \: 4squares\\ + area \: of \: small \: rectangle \\ \longrightarrow {150m}^{2} + {100m}^{2} + {50m}^{2} \\ \longrightarrow {300m}^{2}$

____________________________________________________________________

Final Answer:

so, the area of the given fig. is

$\longrightarrow {300m}^{2}$
