Side 1 + Side 2 + Side 3 = Perimeter
First isosceles triangle: 2a + 2a + b = 4a + b
Second isosceles triangle: b/2 + b/2 + 4a = 4a + b
Area of rhombus = d1 × d2
= 12 × 16 = 192
Area of rhombus is also b × h
Assuming the side as base,
192 = b × h
192 = 10 × h
h = 192/10 = 19.2 in

Step-by-step explanation:
Answer:
48
Step-by-step explanation:
Area of unshaded = area of the whole figure - area of shaded
= (x + 5)^2 - x^2
= x^2 + 10x + 25 - x^2
= 10x + 25 Answe
