Using the Pythagoras theorem since it is given that it is a right angled triangle
let us name the triangle as A, B, C with B as right angle
AB^2 + BC^2 = AC^2 ( Pythagoras theorem)
where AB = 4 , BC = 7 , AC = x
It would be: 2.836x10^-5
Hope I helped :) Let me know if you have any more questions!

Answer:
Explanation:
Rewrite in slope intercept form "y = mx + b"
Here the slope is 4/3 and y-intercept is -4
Perpendicular lines has negatively inverse slope.
→ per. slope = -(slope)⁻¹ = -(4/3)⁻¹ = -3/4
Area of the field should be 9*10 = 90 square feet.
a bag of grass seeds cover 15 square feet.
so if you need to know how many bags should be used, then,
Total area of field/ area covered by 1 bag of grass seeds.
= 90/15 = 6 bags
he needs to use 6 bags of grass seeds to cover the whole field.
I don't think there are any 'hidden' questions, though you can consider the 2nd part of the question I guess. (how many bags of seed will Paul...)
