The Area of two windscreens of a bus is 1.21m² in a photograph of the bus the windscreen appears as a rectangle 12 cm by 3cm.find the length and breath of the real windscreen

Answer 1

To find the length and breadth of the real windscreen, we need to convert the measurements from the photograph to actual size.

Given:
Area of the two windscreens in the photograph = 1.21m²
Length in the photograph = 12 cm = 0.12m
Breadth in the photograph = 3 cm = 0.03m

Let the length of the real windscreen be x meters and the breadth be y meters.

Area of one windscreen in the photograph = 0.12m * 0.03m = 0.0036m²

Area of two windscreens in the photograph = 2 * 0.0036m² = 0.0072m²

Since the area of two windscreens in the photograph is 1.21m², we can set up the following equation to find the real length and breadth of the windscreen:
0.0072m² = 1.21m²
x * y = 1.21

From this equation, we can calculate the real length and breadth of the windscreen. Let's solve for x and y:

x = 1.21 / y

Substitute this into the equation x * y = 1.21:

(1.21 / y) * y = 1.21
1.21 = 1.21
1 = 1

This equation holds true for all values of y. Therefore, we cannot determine the exact values of length and breadth of the real windscreen from the given information.
