×imagine this is a flattened pyramid box. When you fold along the dotted lines you can see which sides are equivalent.
Add up the areas of each piece.
Two identical rectangular pieces 7 × 10
2(7)(10) = 140
One small rectangular piece 6 × 7
7(6) = 42
Two identical triangles
2(0.5)(6)(8) = 48
Add up all the pieces
140 + 42 + 48 = 230
Answer:
m = -10
Step-by-step explanation:
0.61m - 1.51m = 9
-0.90m = 9
mutiply both sides by -1.111111111111, twelve 1's after the decimal point
also to find what number u need to multiply to make -0.9m to m, divide 0.9 by 1 and that equals 1.111111111111 so yea a lot of ones haha
m = -10
Area= 1/2(height)×(base↓1+base↓2)
Area=1/2(3)×(8+11)
Area=1/2(3)×(19)
Area=1/2(57)
Area=57/2 OR 28.5
Thus, the area of the trapezium is 28.5inches^2
Answer:6.5 centimeters
Step-by-step explanation:10 kilo + 10 kilo + 5 kilo
Should give you 6.5 centimeters if 10 is 3 centimeters
