Question

Findtheareaofthefollowing,usingunitscorrectly.a) Arectanglewithlength6cmandwidth12cm.b) Atrianglewithbase17metersandheight8meter

Answer 1

`A)\text{Area}=72cm^2`
`B)\text{Area}_t=68m^2`

Step-by-step explanation

Step 1

find the area:

Arectanglewithlength6cmandwidth12cm.

the area of a rectangle is given by:

`\begin{gathered} \text{Area}=\text{length}\cdot\text{width} \\ \end{gathered}`

so, Let

length=6 cm

width=12 cm

replace in the formula

`\begin{gathered} \text{Area}=\text{length}\cdot\text{width} \\ \text{Area}=6\text{ cm }\cdot\text{ 12 cm} \\ \text{Area}=72cm^2\text{= 72 square centimeters} \end{gathered}`

Step 2

find the area:

Atrianglewithbase17metersandheight8meter​:

the area of a triangle is given by:

`\begin{gathered} \text{Area}_t=(base\cdot heigth)/(2) \\ \end{gathered}`

Let

base= 17 m

heigth= 8 m

replace,

`\begin{gathered} \text{Area}_t=(base\cdot heigth)/(2) \\ \text{Area}_t=\frac{17\text{ m}\cdot\text{ 8 m}}{2} \\ \text{Area}_t=(136m^2)/(2) \\ \text{Area}_t=68m^2=68\text{ square meters} \end{gathered}`

I hope this helps you
