12 the base times the height
12*6.5 = 78 square cm
Perimeter = 12+12+3+3 = 30m
12+12=24
The perimeter would be 36 inches.
Base = 102/12 = 8.5 feet Perimeter = 12+8.5+12+8.5 = 41 feet
If it's a rectangle then:- Area = 15*12 = 180 square units Perimeter = 15+15+12+12 = 54 units of measurement
12 the base times the height
12 the base times the height
72
The perimeter of a rectangle is simply the sum of its four sides. In this case - 12 + 19 + 12 + 19 = 62
The perimeter of a rectangle does not provide enough information to determine its dimensions.Let 0
If it is a rectangle then area = base × height = 7cm × 12 cm = 84 cm². If it is a triangle (more likely given the terminology used) then area = ½ base × height = ½ × 7 cm × 12 cm = 42 cm²
If the rectangle is 12 feet long and has a perimeter of 40, then the height must be 8. If it is made 6 feet longer, it will have a length of 18 and a height of 8. The new area will be 144.
A=b*h area = base (times) height P=2b + 2h perimeter = 2 (times) base (plus) 2 ( times) height A= b*h 12 = b*h 12/b = h let x = b h = 12/x since x = b and h = 12/x therefore P = 2x + 2(12/x)
Area Rectangle = 12 * 8 = 96 sq. in.Area Triangle = 1/2 base * height -> 96 = 16 * height -> 96 / 16 = height = 6 in.
If it is a rectangle then the perimeter is 78ft
