Answer:
im guessing 6 is your base and your height is 15 3/4.
Formula of a triangle we must remember:
BH x 1/2 (basically dividing by 2)
94.5 (fraction form will be: 94 1/2)
94.5 divided by 2 = 47.25 <---------- decimal form
94 1/2 divided by 2 = 47 1/4 <------- fraction form
In this case, you are asked to bring the area with m2 unit but the length(120yd) and width(50yd) are in yd. Then, you need to convert the unit into m2. The formula of rectangle area should be length * width.
So, the equation should be:
area = length * width= (120yd * 91.44cm/yd * 1m/100cm) * (50yd * 91.44cm/yd * 1m/100cm) = 5016.76 m2
Answer:
Prime numbers less than 20 are 2, 3, 5, 7, 11, 13, 17 and 19
Step-by-step explanation:
Length of wall is 16 feet and breadth is 4 feet.
Step-by-step explanation:
- Step 1: Given area = 64 sq. ft, length is breadth + 12 ft. Let breadth be b.
So length, l = b + 12
- Step 2: Substitute in area for rectangle = length * breadth
⇒ (b + 12) * b = 64
⇒ b² + 12b = 64
⇒ b² + 12b - 64 = 0
- Step 3: Solve for b using equation for finding roots of quadratic equation
Roots = (- b ±√b² - 4ac)/2a
⇒ b = (- 12 ±√144 - 4 * 1 * - 64)/2
= (-12 ±√144+256)/2 = (-12±√400)/2
= (-12±20)/2
= 4, -16 (negative is neglected)
⇒ breadth is 4 feet
- Step 4: Length = b + 12 = 16 feet
