Question

7. Perimeter of a rectangular field 50 m long and 30 m
wide is equal to the perimeter of a square field. Find
the area of the square field.​

Answer 1

Step-by-step explanation:

rectangular field

l=50

b=30

perimeter=2×l+b

=2×50×30

=2×1500

=3000

Answer 2

Answer:

Given

Length of the field = 50 m

Breadth of the field = 30

perimeter of rectangular field= perimeter of square field

2(l+b) = 4*side

2(50+30)=

160= 4*side

side =160/4

side=40

now,

area of square =side *side

=40*40

=1600 ANSWER
