1 and3can form the triangle
As the sum of 2sides is greater then the 3rdside
Like for first one
12+14>18
26>18
Yes
14+18>12
32>12
Yes
12+18>14
30>14
Yes
so the first set of sides can become a triangle
Answer:
1. 375
2. 294
Step-by-step explanation:
Area of a trapezoid
A = 1/2 (b1+b2) *h where b1 and b2 are the top and bottom of the trapezoide
1.
A = 1/2 (14+36) *15
= 1/2 (50)*15
= 25*15
375
A = 1/2 (21+7) *21
= 1/2 (28)*21
= 14*21
294
The answer is (if going by letters A-D) D
