Area of the rectangle: {base times height}
4cm x 8cm = 32cm^2

Area of the triangle: {base times height divided by two}
(4cm x 11cm) : 2 = 22cm^2

Total area = 22cm^2 + 32cm^2 = 54cm^2

Answer:

54cm^2

Step-by-step explanation:

You need to calculate area of the given figure. To solve this there are two figures together, triangle and rectangle.

first find area of rectangle given length = 8 cm and breadth = 4cm

therefore area of rectangle = l * b = 8 * 4 = 32 cm^2

To find area of triangle:

The triangle itself is divided into two right angled triangle.

Now base of one right angled triangle will be 4/2 = 2cm

Area of rt. angled trangle = 1/2 * b*h = 1/2 * 2 * 11 = 11cm^2

Therefore area of whole triangle = 11*2 = 22cm^2 (since there are two rt.angled triangle)

Total area of given figure = 32 + 22 = 54 cm^2

now, with that template in mind, let's see

3 units to the right, that means C/B = -3 so hmm C = -3 and B = 1 will do, -3/1 = -3

vertical stretch by 2, so A = 2
reflected over the x-axis, so that means is flipped upside-down, so A = -2 then

and shifted down by 3, do D = -3

$\bf f(x)={{ A}}(\mathbb{R})^{{{ B}}x+{{ C}}}+{{ D}}\implies f(x)={{ -2}}(\mathbb{R})^{{{ 1}}x-{{ 3}}}-{{3}}\\\\\\ f(x)={{ -2}}(3)^{{{ }}x-{{ 3}}}-{{3}}$

Given that the perimeter of a rectangle is 64cm and its length is 20cm find its area

Sladkaya [172]

240 cm. The total perimeter minus twice the length. That would be 24. Then divide 24 by 2 to get your width. Then multiply the length times the width or 20 times 12

I need help with question number 6. State how the property is being used?

Lunna [17]

Answer:

Step-by-step explanation:

If say, the + was not shown before the brackets so it looked like x(1+2) + x(1+2) then it would become distributive, allowing you to add first then multiply. The equation doesn't allow you to multiply even though brackets indicate different.
