Answer:
Her model is 37 times as tall as Ben's.
Step-by-step explanation:
70 11/12 ÷ 5 3/4
851/12 ÷ 23/4
851/12 x 4/23
37/1 x 1/1 = 37 times as tall

Step-by-step explanation:
Given in the question that,
length of the diagonal of a square = 6√2
As we know that a square have all lengths equal in size and lengths are perpendicular to each other so to solve this question we will use pythagorus theorem
hypotenuse² = base² + height²
here,
hypotenuse is the diagonal of the square
base and height side length of the square
Plug value in the formula
6√2² = l² + l²
36(2) = 2l²
72 = 2l²
l² = 72/2
l² = 36
take square root on both sides of the equation
l = √36
<h3>l = 6</h3>
