Question

The areas of two panels of a spacecraft are given below.
The combined area of both the panels is .

• A. 5.52$\times {10}^6$
• B. 37.02$\times {10}^7$
• C. 3.702$\times {10}^7$
• D. 5.52$\times {10}^6$

Answer 1

The correct option is C 3.702$\times {10}^7$

Given,
Area of the first panel
= $2.02\times {10}^6{\text{in}}^2$

Area of the second panel
= $3.5\times {10}^7{\text{in}}^2$

Combined area
= Area of the first panel + Area of the second panel
$=2.02\times {10}^6+3.5\times {10}^7$
$=2.02\times {10}^6+35\times {10}^6$
$=(35+2.02)\times {10}^6$
$=37.02\times {10}^6$

Therefore, the combined area of the pannels is $37.02\times {10}^6{\text{in}}^2$.
