Jim is designing a seesaw for a children's park. the seesaw should make an angle of 45° with the ground, and the maximum height to which it should rise is 1 meter, as shown below: what is the maximum length of the seesaw?

√2 meter

Step-by-step explanation:

45° incline will make an isosceles right triangle

length of seesaw:  √1² + 1² = √2

i can't see the picture : /

to find the perimeter of the rectangle this is the expression:

x-9+x-9+3x-4+3x-4=138

if we simplify it:

8x-26=138

remember, 138 is what it all adds up to

the length is 11.5cm

the width is 57.5cm

the area is 661.25cm^2
