Question

Find the length of rectangle whose perimeter is 100 m and breadth is 20 m class 6 book

Answer 1

Answer:

Length is 30m

Step-by-step explanation:

Given:

Perimeter(P) = 100m

Breadth(b) = 20m

We know Perimeter = 2 x (length + breadth)

P = 2 x (l + b)

100 = 2 x (l + 20)

50 = l + 20

l = 30m
