Question

find the perimeter and area from the following figure. all cornors are right angled.
the values may not be clear
they are:2m,4m and 1.5m​

Answer 1

Answer:

area is 14 m².

perimeter is 14 m.

Step-by-step explanation:

area of figure 1= 2×4

=8 m²

area of figure 2=1.5×4

=6m²

area of figure = 6+8

= 14m²

perimeter of figure = 2+4+4+1.5+6+6.5

= 24m

Answer 2

Step-by-step explanation:

Length = 24.5 m

Breadth = 18 m

∴ Area of the rectangle = Length × Breadth

= 24.5 m × 18 m

= 441 m2

(ii) Length = 12.5 m

Breadth = 8 dm = (8 × 10) = 80 cm = 0.8 m [since 1 dm = 10 cm and 1 m = 100 cm]

∴ Area of the rectangle = Length × Breadth

= 12.5 m × 0.8 m

= 10 m2
