Question

Urgent!! Pls help ASAP!!!

Answer 1

area = bh / 2

Since you already know the area and height, the equation becomes:

150 = b(20) / 2

divide 150 by 20:

7.5

Now, multiply 7.5 by 2:

15

Now the equation is:

150 = (15)(20)/2

You can check your work by multiplying 15 by 20 and dividing the answer by 2 to insure that you get 150:

15 * 20 / 2 = 150

Your answer would be:

C. 15 cm

Answer 2

the answer is c ) 15 cm

a = (h×b)/2

a= (15×20)/2

a= 300/2

a= 150 cm²
