Question

Can someone please tell me the answers

Answer 1

3.
`190yd^(2)` 4.
`45cm^(2)`

Explanation:

Area of trapezoid = half the sum of the parallel sides/ bases x the perpendicular height

3. Area of trapezoid =
`((b_(1) +b_(2) )h)/(2)`

=
`((17+21)10)/(2)`

=
`(380)/(2)`

=
`190yd^(2)`

4. Area of trapezoid =
`((b_(1) +b_(2) )h)/(2)`

=
`((4.5+5.5 )9)/(2)`

=
`(90)/(2)`

=
`45cm^(2)`

hope this helps :)
