Question

What is the perimeter of a rectangle with a base of 9 ft and a height of 10 ft?

Answer 1

`\:\:\:\:\:\:\longrightarrow \sf \underline{P = 2 ( x +y)}\\`

`\:\:\:\:\:\:\longrightarrow \sf\underline{Perimeter_((rectangle) ) = 2 ( Height +Base)\: unit}\\`

Where-

• P = Perimeter of rectangle
• x = Height of recatngle
• y = Base of rectangle

As per question, we are given that -

• Height, x = 10 ft
• Base, y = 9 ft

We are asked to find out the value of perimeter for the given rectangle. Now that we have all the required values, so we can put them into the formula and solve for the perimeter -

`\:\:\:\:\:\:\longrightarrow \sf\underline{Perimeter_((rectangle) ) = 2 ( Height +Base)\: unit}\\`

`\:\:\:\:\:\:\longrightarrow \sf Perimeter_((rectangle) ) = 2\bigg(10+9\bigg)\\`

`\:\:\:\:\:\:\longrightarrow \sf Perimeter_((rectangle) ) = 2 * 19\\`

`\:\:\:\:\:\:\longrightarrow \sf \underline{Perimeter_((rectangle) )=38 \:ft }\\`

• Therefore, the perimeter of the rectangle is 38 ft.
