Question

Find the perimeter of a rectangle whose area is 500 cm² and breadth is 20 cm.

Open in App

Solution

Area = 500 cm²
Breadth = 20 cm
Area of rectangle = Length $\times$ Breadth
Therefore
Length = $\frac{A r e a}{B r e a d t h}$ = $\frac{500}{20}$ = 25 cm
Perimeter of a rectangle = 2 (Length + Breadth)
= 2 (25 + 20) cm = 2 $\times$ 45 cm = 90 cm

Find the perimeter of a rectangle whose area is 500 cm² and breadth is 20 cm.

Area = 500 cm²
Breadth = 20 cm
Area of rectangle = Length $\times$ Breadth
Therefore
Length = $\frac{A r e a}{B r e a d t h}$ = $\frac{500}{20}$ = 25 cm
Perimeter of a rectangle = 2 (Length + Breadth)
= 2 (25 + 20) cm = 2 $\times$ 45 cm = 90 cm
