The area of a rectangle is 72 square metres. The length of the rectangle is twice the width. Find the width of the rectangle.

1 answer:

6 0

Answer: Width = 6m

Working:
Find common factors of 72:
1, 2, 3, 4, 6, 8, 9, 12, 18, 24, 36, 72

Work out which ones multiply together to make 72 and as the question states that the length is twice the width, we need to find two numbers that multiply to make 72 and one of the numbers is double the other number.

These numbers would be 6 and 12. (6 x 12 = 72)

Therefore:

Area = 72m²
Width = 6m
Length = 12m

g(x) = -2

f(x) = x + 4

f(-2) = -2 + 4

f(-2) = 2

ONLY ANSWER NO WORK WILL MARK BRAINLIEST

Alright, here goes:
For this question, you are asked about the median and Interquartile Range(IQR), so first you need to understand what that means.
The IQR is the box in the middle of the box-and-whisker-plot. The question asks for the place to have a small IQR, so the most likely places are Pensacola and Jacksonville.
The question is also asking for a high median temperature. The median is the line in the middle of the plot.
The median of Pensacola's plot is higher than the median of Jacksonville, so Pensacola Beach is your answer :)

for triangular part:base=8in, height=3in

area of the given fig:

area of the given fig:area of 2 triangles +area of rectangle 

 $→2( \frac{1}{2} \times b \times h) + l \times b \\ →2( \frac{1}{2} \times 8 \times 3) + 12 \times 8 \\ →24 + 96 \\ → {120in}^{2}$
