Question

Find the perimeter of rectangle whose area is 12whole1/4 cm square and breadth is 2whole1/3 cm

Answer 1

Answer:

breadth = 7/3 cm

area = 49/4 sq. cm

length × breadth = 49/4

length = 49/4 × 3/7

length = 21/4 cm

Answer 2

Let the length be x

ATQ,

Area=l×b

49/4=l×7/3

l=49/4÷7/3

=21/4= 5whole1/4

so, the length is 5whole1/4cm

Perimeter=2(l+b)

=2(21/4+7/3)

=2×91/12

=91/6

so it's perimeter is 15whole1/6cm

Hope it helps you.
