Answer:

The width of the bigger phone is 2.99 in

Explanation:

Given

W_1 = 2.6in

L_1 = 5.4in

L_2 = 6.21in

See attachment for the measure of cell phones

Required

Determine the width of the bigger version (L2)

To do this, we make use of the following equivalent ratios.

L_1 : W_1 = L_2 : W_2

This gives:

5.4\ in : 2.6\ in  : 6.21\ in : W_2

Express as fractions

\frac{5.4\ in}{2.6\ in} = \frac{6.21\ in}{W_2}

\frac{5.4}{2.6} = \frac{6.21\ in}{W_2}

Make W2 the subject

W_2 = \frac{6.21 * 2.6\ in}{5.4}

W_2 = \frac{16.146\ in}{5.4}

W_2 = 2.99\ in
