Answer 1

Didn't see this one before, sorry.

(22) A=LW so W=A/L = (25/54) / (5/9) = (25/5)(9/54)= 5/6 miles

(23) 18 = .75 c or c=18/.75 = 18/(3/4) = 18(4/3) = 24 students

(24) 5(d+1) = 5d + 5(1) = 5d + d Answer: 5d+5

(25) Four triangles and a square:

4(1/2)(5.1)(5.95) + (5.1)^2 = 86.7 sq cm

Answer 2

Your answer is 86.7 cm².

First we can find the area of one triangle by doing 1/2 × 5.95 × 5.1, which is 15.17 cm², and since there are 4 triangles, we can multiply this by 4 to get 60.69 cm² as the total area of the triangles.

Then we can find the area of the square by doing 5.1 × 5.1 = 26.01, and then add it on to 60.69 to get 86.7.

I hope this helps!
