Eth enlarged the triangle below by a scale of 5.

levacccp [35]

Answer:

She should have multiplied one half (4)(3.5) by 5 squared.

Step-by-step explanation:

We are given that

Base of triangle=b=4 cm

Height of triangle=h=3.5 cm

Area of triangle= $\frac{1}{2}bh=\frac{1}{2}(4)(3.5) cm^2$

After enlarged

Scale factor=5

New base of enlarged triangle=b'=4(5) cm

Height of enlarged triangle=h'=3.5(5) cm

Area of enlarged triangle= $\frac{1}{2}4(5)(3.5\times 5)=\frac{1}{2}(4)(3.5)(5^2) cm^2$

But Beth wrote

Area of enlarged triangle= $\frac{1}{2}(4)(3.5)(5)=35 cm^2$

She should have multiplied one half (4)(3.5) by 5 squared.
