Answer:
A =315 cm^2
Step-by-step explanation:
The area of a trapezoid is found by
A = 1/2 (b1+b2) *h
where b1 and b2 are the lengths of the bases and h is the height
A = 1/2 ( 13+29) *15
A = 1/2 (42)* 15
A =315 cm^2
I multiplied $15 by 230% and then added my answer(which was 34.5) because subtracting it wasn't an option and got $49.50
Answer: length: 7cm
width:4cm
Step-by-step explanation:
Area: L × W
7×4=28
Perimeter =L±L+W+W
7+7+4+4=22
