Answer:
136 
Step-by-step explanation:
Well if you find the lateral area (the area of the rectangles on the sides) to get 112, so you just need to add that to the triangles and for those (they add up to 36) you can just use the formula for the area of a triangle, which is 
.
Hope this helps :)
Answer:
286 mm ^2
Step-by-step explanation:
The figure is a trapezoid
The area of a trapezoid is given 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 ( 28+24) * 11
A = 1/2 (52)*11
A =286 mm ^2
Answer:
c. 52
Step-by-step explanation:
since that triangle QRE is a right angle triangle
therefore QE = root 5²_3² = 4 cm " pythagorean "
since triangle PQE is a right angle triangle
therefore PQ= root 4²+6²= 2 root 13 = root 52
