What is the area of the rectangular billboard?

Sides: 20√7 ft and 7√8 ft

Well, if comedy was an Olympic sport, I'd definitely win a gold medal! Now, let's get down to business. To find the area of a rectangle, you simply multiply the lengths of its sides together. So, in this case, we have a side length of 20√7 ft and another side length of 7√8 ft. Get ready for some math magic!

Drumroll, please!

The area of the rectangular billboard is:

20√7 ft × 7√8 ft = 140√56 ft²

And if you feel like flexing your math muscles, you can simplify it to:

140√(4 × 14) ft² = 280√14 ft²

I hope you found that both informative and hilarious!

To find the area of a rectangular billboard, you need to multiply the length by the width. In this case, the length is given as 20√7 ft and the width is given as 7√8 ft.

To multiply these two values, you can simply multiply the numbers outside the square roots and multiply the square roots separately.

Let's break it down step-by-step:

Step 1: Multiply the numbers outside the square roots:
20 x 7 = 140

Step 2: Multiply the square roots:
√7 x √8 = √(7 x 8) = √56

Step 3: Simplify the square root:
√56 = 2√14

Step 4: Multiply the numbers outside the square root by the simplified square root:
140 x 2√14 = 280√14

Therefore, the area of the rectangular billboard is 280√14 square feet.

To find the area of a rectangular billboard, we need to multiply the length by the width. In this case, the length is given as 20√7 ft and the width is given as 7√8 ft.

To calculate the area, we can use the formula:

Area = Length * Width

Substituting the given values:

Area = (20√7 ft) * (7√8 ft)

To simplify this expression, we can multiply the numbers outside the square roots and multiply the numbers inside the square roots separately:

Area = (20 * 7) * (√7 * √8) ft^2

The product of 20 and 7 is 140, and the square root of 7 multiplied by the square root of 8 can be simplified as √(7 * 8) or √56.

Area = 140 * √56 ft^2

To further simplify the expression, we can factor √56 as √(4 * 14) or 2√14.

Area = 140 * 2√14 ft^2

Now, multiplying the numbers outside the square root:

Area = 280√14 ft^2

Therefore, the area of the rectangular billboard is 280√14 square feet.

Multiply the numbers together. A of rectangle = length x width
