Question

8. The area of a square field with side 45 m is
the same as the area of a rectangular field with
breadth 25 m. Find the length and perimeter of
the rectangular field.​

Answer 1

Answer:

length of the rectangular field is 81m

Perimeter of the rectangular field is 212m

Step-by-step explanation:

Area of the square field = 45 m x 45 m = 45x45 $m^2$

Let's assume that the length of the rectangular field is x

According to the problem:

$25x = 45^2$

∴ $x = \frac{45 . 45}{25} m = 81 m$

∴ Perimeter of the rectangular field $= 2 (length + breadth)$ = 2(81 + 25) m = 212 m
