Answer:
Perimeter = 64cm
Area = 192cm^2
Step-by-step explanation:
Base = 24cm
Height = xcm
(x+4)^2 = x^2 + (12)^2
x^2 + 8x + 16 = x^2 + (12)^2
8x = x^2 - x^2 + 144 - 16
8x = 128
x = 128/8
x = 16
Perimeter = 24 + 16+ 4 + 16 + 4
Perimeter = 64cm
Area =
{S = 64/2 = 32 ; A = 24 ; B = 20 ; C = 20}
Area =
Area =
Area =
Area = 8*2*12
Area =
