Question

Area of rectangle or triangle

Answer 1

Answer:

48 cm²

Step-by-step explanation:

shaded area = area of rectangle - area of triangle

area of rectangle = 7 × 8 = 56 cm²

area of triangle = $\frac{1}{2}$ bh ( b is the base and h the height )

Here b = 7 - 3 = 4 cm and h = 8 - 4 = 4 cm

area of triangle = $\frac{1}{2}$ × 4 × 4 = 2 × 4 = 8 cm²

Then

shaded area = 56 - 8 = 48 cm²
