Question

find the rectangle if perimeter is 88 CM length 30 cm and breadth ? what find the breadth

Answer 1

Given

Perimeter of rectangle = 88 cm

Length = 30 cm

To Find

Breadth of rectangle = ?

Solution

Let the breadth of rectangle be x

We know that

Perimeter of rectangle = 2 ( length + breadth )

88 = 2 ( 30 + x )

88 = 60 + 2x

2x = 88 - 60

2x = 28

x = 14

so the breadth of the rectangle is 14 cm

Answer 2

⇒Perimeter=88 cm
⇒2(l+b)=88
⇒l+b=44
⇒b=44 - 30        [∵l=30] Given
 ∴, b = 30 cm
