Ric received $3.00 of change. First, you multiply 4 by $1.25 to get $5.00. Then, the pen cost $2.00 because 2 is 2/5 of 5. Next, you add 2 and 5 together to get $7.00. Lastly, you subtract 7 from 10 ($10.00-$7.00) to get your change, $3.00. Hope it helps :)

A triangle has an area of 900m2 . If a parallelogram has the same height and base as the triangle, what is the area of the paral
timama [110]

Answer:

1800 m^{2} is the area of parallelogram.

Step-by-step explanation:

Given that:

Area of a triangle = 900 m^{2}

To find:

Area of a parallelogram which has same height and base as that of the given triangle.

Solution:

First of all, let us have a look at the formula for Area of a parallelogram:

Area_{Par} = Base \times Height ...... (1)

So as to find the area of a parallelogram, we need to have the product of Base and Height of Parallelogram.

Now, let us have a look at the formula for area of a triangle:

Area_{Tri} = \dfrac{1}{2} \times Base \times Height

Given that height and base of triangle and parallelogram are equal to each other.

So,the product of base and height will also be equal to each other.

900 = \dfrac{1}{2} \times Base \times Height\\\Rightarrow Base \times Height = 2 \times 900\\\Rightarrow Base \times Height = 1800\ m^2

By equation (1):

<em>Area of parallelogram = 1800 </em>m^{2}<em> </em>
