Answer 1

Step-by-step explanation:

let l be the length of altitude and b is the base

given base is equal to 3/4 of altitude

b= (3/4)l

area = 1/2×base× height

Area = 1/2×3/4×l=3/8²

of l is increased by 3 , decreased by 2

(l+3 )be the new altitude

(b-2)be the new base

given

(3/8) l²= (1/8)×(l+3)×(3l-8)

3l²= 3l²-l-24

l= 24 (altitude)

b= 3/4l= 3/4×24= 18 (base length)
