Question

The length and breadth of a rectangle are in the ratio 4:8. If the breadth is 88 cm, find the length

Answer 1

Answer:

44cm

Step-by-step explanation:

let the ratio be x

length=4x

breadth=8x

8x = 88

x = 11

length=4x

= 4×11

=44 cm

so, length =44cm

Answer 2

Correct Question :-

The length and breadth of a rectangle are in the ratio 4:8. If the perimeter is 88 cm, find the length.

Answer :-

➡ The length of the rectangle is 29.36 cm .

Explanation :-

$\sf{\huge{\underline{\purple{Given :-}}}}$

• The length and breadth of a rectangle are in the ratio 4:8.

• The perimeter is 88 cm.

$\sf{\huge{\underline{\pink{To\:Find :-}}}}$

• The length of the rectangle.

$\sf{\huge{\underline{\blue{Solution :-}}}}$

Let the sides be x,

The length and breadth of a rectangle are in the ratio 4:8.

• The breadth = 4x

• The length = 8x

We, know the perimeter of a rectangle = 2 ( l + b )

The perimeter is 88 cm.

2 ( l + b ) = 88 cm.

➝ 2 ( 8x + 4x ) = 88

➝ 2 × 12x = 88

➝ 24x = 88

➝ x = 88/24

➝ x = 3.67

The breadth = 4x = 4 × 3.67 = 14.68 cm

The length = 8x = 8 × 3.67 = 29.36 cm
