Question

Can you resolve this? A= Area P= Perimeter AT= Total Area plis help D:

Answer 1

Answer:

in steps

Step-by-step explanation:

upper square:  P = 20x² + 8

side: P/4 = 5x² + 2

A = side² = (5x² + 2)² = 25x⁴ + 20x² + 4

Middle equilateral Triangle: A = x² + 4x + 4       base = 2x + 4

A = base x height / 2

(x + 2)² = 2 (x + 2) x height /2

height = x + 2

perimeter = 2 (x + 2) x 3 = 6x + 12

Lower trapezoid: A₁ = 2x² + 24x + 40 = 2 (x² + 12x + 20) = 2 (x + 2) (x + 10)

A₁ = (x + 10)² = 2 (x + 2) (x + 10)

x + 10 = 2x + 4

x = 6

A₂ = (2x + 4) (x + 10) / 2 = (16 x 16) / 2 = 128

A₁ = (6 + 10)² = 256

AT = 256 + 128 = 384
