Question 7

Please help me out.
Correct answer will be marked brainlest.

60 cm²

Step-by-step explanation:

The shaded area is calculated as

area of trapezium - area of white triangle

The area (A) of trapezium is calculated as

A = h( b₁ + b₂)

where h is the perpendicular height and b₁, b₂ the parallel bases

Here h = 12, b₁ = 14 and b₂ = 10 , then

A = × 12 × (14 + 10) = 6 × 24 = 144 cm²

The area (A ) of the white triangle is calculated as

A = bh ( b is the base and h the height )

Here b = 14 and h = 12

A = × 14 × 12 = 7 × 12 = 84 cm²

shaded area = 144 - 84 = 60 cm²

were is the equation
