A rectangle measures 2 1/2 meters by 1 3/4 meters. What is its area?

Mathematics

REY [17]2 years ago
3 0

Answer:

4 3/8

Step-by-step explanation:

1. We can use the formula

<em>Area = L (length) x W (width)</em>

2. The area is unknown so we can substitute it for<em> a</em>

<em>   </em>The length and width are both known, so we can plug them in.

<em>a= 2 1/2 x 1 3/4</em>

3. Solve by multiplying

<em>a=4 3/8</em>

The width of the rectangle
Nikolay [14]

Answer:

84cm^2

Step-by-step explanation:

P=2l+2w

We are given,

P=40cm

l=2w+2

Plug these into the first formula and solve for the dimensions,

length and width, of the rectangle:

40=2(2w+2)+2w              Simplify

40=4w+4+2w

40=6w+4

36=6w

6=w OR the width is 6cm, therefore,

the length is

l=2(6)+2

l=14cm

To calculate the area of a rectangle, A=lw,

plug the length,14cm, and the width, 6cm, into this formula

A=(14)(6)

A=84cm2 OR the area of the rectangle is 84cm^2

SashulF [63]
V(t) = 2t^2 - 3t - 3

for an acceleration a(t),
a(t) = d (v(t)) / d t
a(t) = 4t - 3

at t=2
a(2) = 8 - 3
a(2) = 5 feet/s^2
