Calculate the area of the following figure.

Llana [10]

Answer:

77 cm²

Step-by-step explanation:

The figure can be decomposed into two rectangles.

✔️Area of rectangle 1:

Area of rectangle 1 = length * width

length = 3.5 cm

width = 8 cm

Area of rectangle 1 = 3.5*8 = 28 cm²

✔️Area of rectangle 2:

Area of rectangle 2 = length * width

length = 14 cm

width = 3.5 cm

Area of rectangle 2 = 14*3.5= 49 cm²

✔️Area of the figure = 28 + 49 = 77 cm²

2.<br> Solve for y.<br> y/8 = 8

mixer [17]

Answer:

y = 64

Step-by-step explanation:

$\frac{y}{8} = 8$

To get rid of the 8 in the denominator, you need to do the opposite of the expression. So opposite of division is multiplication. My multiplying each side by 8, you can get rid of the 8 in the denominator. Because if you divide 8 by 8 it is 1.

$\frac{y}{8}*8 = 8 * 8$

y = 64

First, rewrite 56 and 45 so that they have a common denominator. Then, use < , = , or > to order 56 and 45 .

mrs_skeptik [129]

56 and 45 common denominators.

56/1 - 45/1

In order, it would be: 46/1 < 56/1
