Question

the length and breadth of a rectangle are in the ratio 4:3 if its perimeter is 154 cm find both dimensions.​

Answer 1

Answer:

Let the ratio be -x

Step-by-step explanation:

4x+3x=154

7x=154

x=154/7

x=22

4x=4

$4 \times 22 = 88$

$3 \times 22 = 66$

Answer 2

Answer:

Let the length of the rectangle be 4x cm and that of breadth = 3x cm

Perimeter = 2(l + b) = 2(4x + 3x) = 2 × 7x = 14x cm

14x = 154

x = 11

Length = 4 × 11 = 44 cm

and breadth = 3 × 11 = 33 cm
