The area
of Joseph’s rectangular homework desk is 1,008 square inches. If the length of his
desk is 42 inches, how wide is his desk?
Its dimensions are 6 inches by 7 inches because 2(6+7)=26 inches and 6*7=42 square inches
2 (x + 2x) = 42 x + 2x = 21 3x = 21 Therefore, x = 7 The width of the rectangle is 7 inches. The length of the rectangle is 14 inches.
A rectangle has two dimensions, length and width. You haven't said what the width is. The perimeter is the distance around the rectangle. Imagine going round it. You would go 42 inches, then a width, then another 42 inches, then another width. In general, the perimeter of a rectangle is twice its length plus twice its width.
If we express the shortest side as x, then the rectangle's length is 3x (as it is 3 times as long as its width).To find the area multiply the length and witdh together.x * 3x = 3x2The area of the rectangle would be 3x2.e.g if the width of the rectangle was 4, the area would be:3 x 42 = 48
Try a rectangle with dimensions of 6 cm and 7 cm, and see what you get.
Area of rectangle: 6 times 7 = 42 square inches
The dimensions of the rectangle are 3 inches by 14 inches
42 <insert unit> squared.
42 inches = 3.5 feet48 inches = 4 feetThe area of a rectangle that measures (42" by 48") is (3.5 x 4) = 14 square feet.
Its dimensions are 6 inches by 7 inches because 2(6+7)=26 inches and 6*7=42 square inches
Assuming that it's a rectangle then:- Area = 42*14 = 588 square cm Perimeter = 42+42+14+14 = 112 cm
42x24=1008
Make it 2 wide and 21 long and you've got it.
For a rectangular table that is 42 inches wide and 78 inches long, a tablecloth measuring at least 60 inches wide by 96 inches long would be ideal. This size allows for a drop of about 9 inches on each side, providing a nice overhang. If you prefer a longer drape, you can opt for a larger tablecloth, such as 60 inches by 108 inches.
2 (x + 2x) = 42 x + 2x = 21 3x = 21 Therefore, x = 7 The width of the rectangle is 7 inches. The length of the rectangle is 14 inches.

The backboard of a basketball goal is typically 1.80 meters by 1.05 meters in area. The diameter of the rim of the basket is 0.45 meters.
