Answer 1

QUESTION:–

Find length when perimeter of rectangle is 56m and breath 700cm.

GIVEN:–

PERIMETER=56m

BREADTH=700cm OR 7m

FIND:–

LENGTH OF RECTANGLE

FORMULA:–

PERIMETER=2(L+B)

SOLUTION:–

let the length be x.Then,

56=2(7+x)

=>56=14 + 2x

=>56‐14=2x

=>42=2x

=>42/2=x

=>21=x

ANSWER:–

LENGTH=21m

Answer 2

Answer:

length =21 m

Step-by-step explanation:

Given: Perimeter = 56m

Breadth =(700/100) = 7 m

To Find: Length

Solution : We know,

. Perimeter = 2(l+b)

56 = 2(l+7)

28 = (l+7)

l = 21 m
