x = 17 cm
Step-by-step explanation:
The lateral area is the area of the four triangles. Each will have an area that is 1/4 of the total, or 544/4 = 136 cm². The area of a triangle is given by ...
A = 1/2bh
136 cm² = 1/2(16 cm)(x) . . . . . . . . use the values shown for base and height
136/8 cm = x = 17 cm . . . . . divide by 8 cm
The measure of x is 17 cm.
