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
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.
