Question

two sides of a parallelogram are in the ratio 4:3. if it's perimeter is 56 cm find the lengths of its sides

Answer 1

let the ratio be 4x and 3x.
4x+5x=56.
7x=56.
x=56/7
x=8.
first length=4×8=32.
second length=3×8=24.

Answer 2

Let 4,3 be 4x,3x.
Opposite sites of a parallelogram are equal.
So the remaining two side are 4x and 3x

Perimeter= sum of all sides.
56 = 4x +3x+4x+3x
56 =14x
14x = 56
X =56/14=28/7
X= 4
Ans: x=4
