Answer:
A=630 in^2
Step-by-step explanation:
Triangles: there are two equal triangles so we can treat them as one rectangle
A = 15 * 14 = 210
Rectangle:
A=30 * 14 = 420
A_total = 210 + 420 = 630 in^2

Answer:
116 cm²
Step-by-step explanation:
a = side length of A
b = side length of B
b = a + 4
b² = a² + 70
(a+4)² = a² + 70
a² + 8a + 16 = a² + 70
8a + 16 = 70
8a = 54
a = 54/8 = 27/4 = 6.75
b² = a² + 70 = 6.75² + 70 = 45.5625 + 70 =
= 115.5625 ≈ 116 cm²
our does your teacher mean 3 significant figures after the decimal point ? then it would be
115.563 cm²
