Answer:
290 cm sq.
Step-by-step explanation:
We can approximate this irregular figure as a trapezoid.
We know the area formula for a trapezoid is A = (1/2)*(base1 + base2)*height
A = (1/2)* (22 cm + 36 cm) * (10 cm)
A = (1/2) *( 58 cm)*10 cm
A = 29 cm * 10 cm
A = 290 cm sq.
Answer:
Since, Multiplication is a shortcut for addition.
Use of Distributive Property is the most familiar alternative way to write 9 x 200.
Distributive Property states that when a number is multiplied by the sum of two numbers, then the first number can be distributed to both of those numbers and multiplied by each of them separately i.e,
9 x 200
First replace 200 as 100+100 then, we have
Now, using distributive property above:
9 x 200 = = 900+900 =1800.
