Answer:
55 cm²
Step-by-step explanation:
side length of square = perimeter/4 = 40/4 = 10 cm.
area of square = side x side = 10 x 10 = 100 cm²
area of triangle #1 = 1/2bh = 1/2(3)(10) = 15
area of triangle #2 = 1/2bh = 1/2(6)(10) = 30
100 - 15 - 30 = 55 cm²
Simply divide 15.7 by 6.28 to get 2.5 :) easy peasy pumpkin pie
4 is equal to 2*2 (double the 2 is 4)
We can get the value of 8*4 on two steps:
1- we multiply the 8 by 2
2- we add the result of the multiplication to itself
This is illustrated as follows:
8*2 = 16
16+16 = 32
