Answer:
Step-by-step explanation:
By formulating a diagram u will form a triangle and u'll need to form a base from the square by finding it's diagonal then get half the diagonal as the base and the slanting height as the hypotenuse to find the height
23.4²+23.4²=DO
D²=1095.12
D=√1095.12
D=33.09
Base=33.09÷2=16.545
H²=88.6²-16.545²
H²=7576.22
H=√7576.22
H=87.04cm
