Question

Explain and Answer!!!!

Answer 1

Divide the arrow into upper triangle and lower rectangle

area of triangle :-

`(1)/(2) * base * height`

`(1)/(2) * 20 * (15 + 8 + 8) \\ (1)/(2) * 20 * 31 = 310`

area of rectangle :-

`length \: * \: width \\ 15 * 20 = 300`

add both the area :-

area of triangle+ area of rectangle = area of arrow

310 + 300 = 610 cm²
