Question

Find the area shaded in yellow please!

Answer 1

A= 1/2(7 + 11)(5)
A = 1/2(18)(5)
A = 45 square units

Answer 2

45 unit²

Explanation:

the yellow shaded area is trapezoid.

And we know area of any trapezoid is represented by A =
`(1)/(2)` (sum of bases ) × ( length between bases)

Bases of the trapezoid measure 7 units and 11 units

Length between bases = 5 units.

Area =
`(1)/(2)(7+11) (5)`

=
`(1)/(2)(18)(5)`

= 9 × 5

= 45 unit²
