Answer:
56 cm²
Step-by-step explanation:
The area (A) of a trapezoid is calculated as
A = h(a + b)
where h is the perpendicular height and a, b the parallel bases
here h = 4, a = 5 + 9 + 5 = 19 and b = 9, thus
A = × 4 × (19 + 9) = 2 × 28 = 56 cm²
Answer:
xy = 72
2x + 2y = 34 (Im assuming uts a rectangle or square)
2 (72/y) + 2y = 34
144 + 2y^2 = 34y
2y^2 - 34y + 144 = 0
y = 9 or 8
So the length is 9 and width = 8
