Do u need help with all of them
The area is 192 cm^2
the sides are 20 20 24 with the base being 24
to figure out the height you have to use Pythagorean theorem of the triangle cut in half so 12^2 + b^2 = 20^2
b= 16 = height
b*h* .5= area 16* 24* .5= 192
Answer:
112.2
Step-by-step explanation:
21g=84
g=84/21
g=4
The answer is B
Answer:
w=14
l=18
Step-by-step explanation:
To find the dimensions, create an equation for its area and solve for each using the area formula A = l*w. The dimensions given are A = 252, w for width and l= w+4 (4 more than the width).

The width is 14 so the length is l=w+4 or l= (14)+4 =18
