Answer: 126.5 square cm</h3>
===================================================
Explanation:
Check out the diagram below. I've drawn a horizontal line to split the orange region into two parts: a triangle on top and a rectangle down below.
The triangle has base 11 cm and height 7 cm. The area is base*height/2 = 11*7/2 = 77/2 = 38.5 sq cm.
The rectangle has area 11*8 = 88 sq cm.
The total area of the entire orange figure is 38.5+88 = 126.5 square cm
Answer:
154
Step-by-step explanation:
Primes less than 20 are:
2, 3, 5, 7, 11, 13, 17, 19
Possible combinations that add up to 20 are:
2 + 5 + 13
2 + 7 + 11
The products are:
2 × 5 × 13 = 130
2 × 7 × 11 = 154
So the largest possible product is 154.
