Question

47 cm

Answer 1

Answer:

I'll setup the problem. But I have a question about the car the equal sides of the isosceles triangle. We'll go with 37 cm

Step-by-step explanation:

you will have to find the areas of the 2 isosceles triangles at either end and the 3 rectangles around the triangles.

Area for the triangles

$A = \frac{1}{2} bh$

b = base of triangle, I'll guess it's 24cm

h = height (draw a line between the vertex of the equal sdes to the base at a right angle, then use Pythagoras to

find the height)

$h = \sqrt{ {37}^{2} - {( \frac{1}{2}b) }^{2}}$

area for rectangles

37x47 + 24x47 + 37x47

sorry it's a little sloppy (I'm on a cellphone)
