Question

Find the area of the following figure.

252
`cm^(2)`

400
`cm^(2)`

312
`cm^(2)`

300
`cm^(2)`

Answer 1

312 cm²

Explanation:

The figure is composed of a rectangle and 2 congruent triangles

area of rectangle = 16 × 12 = 192 cm²

area of 2 triangles = 2 ×
`(1)/(2)` × 12 × 10 = 12 × 10 = 120 cm²

Area of figure = 192 + 120 = 312 cm²
