<u>Answer:</u>
- 31 mm² is the surface area.
<u>Step-by-step explanation:</u>
<u>We know that:</u>
- Surface area of triangle = 3(1/2 x 4 x 4) + (1/2 x 4 x 3.5)
<u>Work:</u>
- 3(1/2 x 4 x 4) + (1/2 x 4 x 3.5) mm²
- => 3(2 x 4) + (2 x 3.5) mm²
- => 24 + 7 mm²
- => 31 mm²
Hence, <u>31 mm² is the surface area.</u>
Hoped this helped.

Answer:
Alright, we have 4 2/5 / 1/4.
First of all, let's convert the mixed number into an improper fraction.
4 2/5 = 22 / 5
Dividing something by 1/4 is the same as multiplying it by 4.
22 / 5 * 4
This is 88 / 5 :)
