Te area of triangle ABC in the figure shown here is 52.5 cm². find the area of triangle BDC​

Answer»

ANSWER:

AREA = 1/2bh

52.5cm² = 1/2*B*7.5cm

52.5cm²/7.5cm = 1/2b

7CM = 1/2b

b = 7cm*2

b=14CM

area of ΔBDC = 1/2bh

                           1/2*14cm*4.5cm

                           7cm*4.5cm

                            31.5cm²
