Answer:
1. 800 cm squared
2. 152 cm squared
Step-by-step explanation:
let break it down
1. 800 cm squared
20 * 7 = 140
20 * 6 = 120
38 - 20 = 18
30 * 18 = 540
now add all of them together
140 + 120 + 540
100 + 100 + 500 = 700
40 + 20 + 40 = 100
700 + 100 = 800 cm squared
2. 152 cm squared
16 * 10 = 160
2 * 2 + 2 * 2 = 4 + 4 = 8
160 - 8 = 152 cm squared
Answer:
Step-by-step explanation:
c because 40-180 is140
25*3.14
78.5
hope this helps yw
1/2 ÷10=1/20 because you multiply the bottoms
3÷1/6= 18 because it is the same as 3×6
