Question

the figure of the question no. 7 is (fig. 5)​

Answer 1

Step-by-step explanation:

=> we have 3 triangles ABC, ACD, AED

=> Area of pentagon = area of (ABC +ACD + AED)

=> Area of ABC = 1/2*(3)*(8) = 12 cm²

=> Area of ACD = 1/2*(7)*(15) = 52.5 cm²

=> Area of AED = 1/2*(5)*(15) = 32.5 cm²

=> Area of pentagon = 12+52.5+32.5

=> Area of pentagon = 97 cm²
