How do i find the area for number 4?

Explanation:

Form a horizontal line as shown below (see attached image). This forms 2 separate smaller rectangles

The total area is therefore 32+9 = 41 cm^2

You can say "square cm" or "sq cm" in place of the "cm^2".

You can solve this in two different ways. In both ways, however, use the formula for the area of a square/rectangle. The formula is:

Area = Length x Width

A = L x W

To solve, divide the shape given into two rectangles. Then, find the areas of the two different rectangles and add them

a

step-by-step explanation:

answer: (-8,4) are the coordinates of a

step-by-step explanation:

let the side of square abcd is x .

thus the area of square abcd is .

now, by the diagram area of triangle ead= 1/2 × ea × ad = 1/2 × ea × x

( because ad is the side of square)

and, according to the question,

the areas of square abcd and right ead are equal.

⇒

⇒ea=2x

thus, ea: ab=2: 1

therefore, point a divides line segment eb into the ratio 2: 1.

⇒ by sectional formula coordinates of a are,

=

=

=(-8, 4)

thus the coordinates of a are (-8,4)
