Question

Find the area of the shaded region in the given figure. (All measurements are in cm). ​

Answer 1

Answer:

75 sq cm

Step-by-step explanation:

area ofΔADB = $\frac{1}{2}$×5×12

=30$cm^{2}$

area of ΔABC=$\frac{1}{2}$×14×15

=105$cm^{2}$

area of shaded region=105-30

Area=75 sq cm

Answer 2

Answer:

Area of triangle ABC:

1/2 × b × h = 1/2 × 14 × 15 = 7 × 15 = 105 sq cm

Area of smaller triangle:

1/2 × b × h = 1/2 × 12 × 5 = 6 × 5 = 30 sq cm

Area of shaded region = 105 - 30 = 75 sq cm
