Answer 1

28cm²

Formula of area of triangle:

1/2 x base x height

Formula of area of rectangle:

length x width

thus,

area of the whole thing:

(1/2 x 7cm x 2cm)+(3cm x 7cm)

=7cm²+21cm²

=28cm²

Answer 2

28
`cm^(2)`

Explanation:

The formula of area for triangles:
`(1)/(2)bh`

`(1)/(2)` * 7 = 3.5 (3.5 *2) = 7

The formula for area of a rectangle: bh

7*3 = 21

Add the areas together 21+7 = 28 squared cm
