To find the area of a rectangle, multiply the length by the width. For instance, if the length is 5" and the width is 6", the area of the rectangle will be 30".

length is 30 width is 10

2

Area = Length * Width = 10*3 = 30 square units.

1,350cm

45*30 = 1350 square units

30*1 = 30 square metres.

Area = 45*30 = 1350 square cm

50 cm2

the answer to number 20 is B...12

Area = height * width Area = 15 * 30 = 450 square units

It is: 240/8 = 30 inches in length

we know,area of rectangle = l * b perimeter= 45*30=1350 cm ^2

you know that: Area=length x width Area=A=30 cm2 and that the width= w and that the length= 2w so, what you do is: 30=2w*w (solve for w) 30=2w2 15=w2 take the square root of 15=w w=3.87cm Your width is 3.87cm your length is 2(3.87)=7.75cm

Imagine the rectangle divided into squares corresponding to length and width... Eg a 6" x 5" rectangle would have 5 rows of six one-inch squares, total 30, which would make its area 30 squinches

The diagonal of a rectangle with the length of 30 yd and the width of 30 yd is approximately 42.43 yd

Multiply 30 by 45 and call it cm2.

30 × 15 = 450 square metres (450m2).

Folders usually have a rectangular shape. The area of a rectangle is the length times the width. So multiply 30 times 24 to get the area in square centimeters.

Area of any square or rectangle = (length) x (width)Length and width are both 30 centimeters.Area = (30cm) x (30cm) = 900 square centimeters

Multiply 6x5. The area is 30 feet squared.

rectangle with 10" length and 2x-4 width 60" area

To get the area of a rectangle, you multiply length x width.

length=2x width=x perimiter=2x+2x+x+x=30= 6x=30 divide by 6, x=5 area=length times width= 2(5)times 5 = 10 times 5= 50yd

The rectangle has a length of 12 cm and a width of 3 cm.
