Question

The length of a wall is 5/4 times of its height. If the area of the
wall is 180 m2. What is the sum of the length and height of
the wall?
[HOTS)​

Answer 1

Answer:

27

Explanation:

Let height = x

length =(5/4)*x

area=l*h=180 sq.m

x*(5/4*x) = 180

height= x = 12

length = 15

Sum = 12+15= 27

Answer 2

Answer:

X = 12

Explanation:

Let height be = x

Length = 5/4x

$x \times \frac{5x}{4 } = 180$

$5x {}^{2} = 720$

$x = 12$

Height = 12 m

Length = 60/4 = 15

Sum = 12 + 15 = 27
