Question

Perimeter of the square field is 240m if perimeter of square is equal to perimeter of rectangle of length 80m
Find:
a. Breadth of rectangle
b. Area of rectangle
c. Area of square

Answer 1

Answer:

Step-by-step explanation:

a) P= 2(l+b)

240m= 2(80+b)m

240cm= 160cm+b

240-160=b

80m=b

b) AREA OF RECTANGLE= 240M (GIVEN)

c) Area of square= 240m

Answer 2

Answer

Given: Perimeter of a square = 240m

: the length of a rectangle = 80m

To find:-

• a. Breadth of rectangle
• b. Area of rectangle
• c. Area of square

Let the breadth of a rectangle be "b"

From the question,

Perimter of a sq.=Perimter of rectangle

=> 240m = l × b

=> 240 = 80 × b

=> b = $\frac{240}{80}$

=> b = 3m

Now,

Area of a rectangle = l × b

= 80 × 3

= 240cm²

For the square,

Perimeter = 240

=> 4a = 240

=> a = $\frac{240}{4}$

=> a = 60m

Area of a square = side ²

= a²

= 60²

= 360cm

Final answer

Breadth of a rectangle = 3m

Area of a rectangle = 240cm²

Area of a square = 360cm²
